Have you been able to successfully run the python example from
<https://github.com/centricular/gstwebrtc-demos/blob/master/sendrecv/gst/webrtc-sendrecv.py> ?

Now I seem to have the issue that I connect callbacks for signals that should run automatically, i.e. “on-negotiation-needed”, but those callbacks never run. Additionally, when I emit signals with attached callbacks such as “create-answer”, the callback is never run. This is evident even in signals such as “set-remote-description” as I construct the proper objects but when I check the remote description after waiting for the promise result it is still None. If anyone has had this problem before, any help would be appreciated.
